Readme for infer-upstream-

[back to package description]


Takes a repo name, and looks up the upstream repository. If there is an upstream repository, writes it to standard out. Otherwise writes nothing.


noon@dev> infer-upstream -r scirate3 -u silky

Another usage:

noon@dev> cd scirate3
noon@dev> git remote add upstream `infer-upstream --using-cwd`

A more interesting usage (and the reason I wrote this) is to use the script. It performs the following task.

For all folders in a given directory:

  • go into each one,
  • if it is a github repo,
  • look up the upstream repo,
  • if we find it,
  • set it as a new remote.


noon@~> cd dev
noon@dev> git clone
noon@dev> infer-upstream/

With upstream set on your repos, you can then run, if you like, which will bring down any incoming changes and give print out a short summary.

  • This script assumes every folder in the ~/dev directory is the clone of a Github repository.
  • Github currently limits you to 60 unauthenticated API requests per hour; this approach uses one API request per folder.
